Notes on editting the part_filter script (version 1.00.11)

The edits noted on this page are responses to a variety of requests I have had about how to change the reject/accept logic of the 1.00.x range of protector versions. They are not supported, mostly have not been tested, and are mostly a bad idea!

1. Relaxing the rules (allowing more file types through)

Please note: I do not recommend any of these changes since they can mean that .exe and other "bad" files can easily get through.

1.1 - To allow "tar" files through without checking (bad idea!)

Edit the "part_filter" file, and look for the text (at or near line 197)..

        application/tar |\ 
        application/x-tar)     unzip_using -f do_tar ;;

And change it to read..

        application/tar |\ 
        application/x-tar)     allow_unchanged ;;

1.2 - To allow "zip" files through without checking (bad idea!)

Edit the "part_filter" file, and look for the text (at or near line 193)..

         application/zip |\ 
         application/x-zip-compressed |\ 
         application/x-zip)     unzip_using -f do_unzip ;;

And change it to read..

         application/zip |\ 
         application/x-zip-compressed |\ 
         application/x-zip)     allow_unchanged ;;

1.3 - To allow "PDF" files through without checking (bad idea!)

WARNING: Please read this first before making the edit below.

Edit the "part_filter" file, and look for the following text (on or near line 233)

         text/*                                  |\ 
         image/*                                 |\ 
         audio/*                                 |\ 
         video/*                                 )
                   allow_unchanged ;;

And add an extra line, so that it now reads..

         application/pdf                         |\ 
         text/*                                  |\ 
         image/*                                 |\ 
         audio/*                                 |\ 
         video/*                                 )
                   allow_unchanged ;;

1.4 - To allow "MS Word" files through without checking (VERY bad idea!)

Please note that there is a very large number of word macro viruses "out there" in the wild. Making this change opens you up to all of them - so make sure that the workstations you used to read you mail with have up-to-date anti-virus software installed - including MS Office protection.

Edit the "part_filter" file, and look for the following text (on or near line 220).

         application/msword                     |\ 
         application/x-msword                   )
                   eval `$LIB_DIR/bin/check_msword $DECODED` ;;

And change it to read..

         application/msword                     |\ 
         application/x-msword                   )
                   allow_unchanged ;;

1.5 - To allow "MS Excel" files through without checking (VERY bad idea!)

Please note that there are quite a few Excel macro viruses "out there" in the wild. Making this change opens you up to all of them - so make sure that the workstations you used to read you mail with have up-to-date anti-virus software installed - including MS Office protection.

Edit the "part_filter" file, and look for the following text (on or near line 224).

         application/vnd.ms-excel                   )
                   eval `$LIB_DIR/bin/check_excel $DECODED` ;;

And change it to read..

         application/vnd.ms-excel                   )
                   allow_unchanged ;;
